IP Connectivity
router(config)#ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/1
default route
OSI layer header contains the address of a destination host that is on another network
Network
decimal equivalent of 10010110
150
value to use in HSRP protocol election process
Priority
This converts domain names into IP addresses.
DNS (Domain Name Server)
Choose the odd-one-out:
● EIGRP and link cost.
● RIPv2 and number of hops.
● OSPF and number of hops and reliability.
● IS-IS and delay and reliability
RIPv2 and number of hops
layer of the OSI model is RSTP used to prevent loops
Data Link
decimal equivalent of 11010111
215
Exactly one active router and
One or more standby routers
two requirements for an HSRP group
When a DHCP server is configured, these two IP addresses should never be assignable to hosts
Network address and Broadcast address
A measure of the trustworthiness of a routing information source.
Administrative Distance (AD)
layer of the OSI model is responsible for segmenting data from a sending host that enables large files to be broken down into smaller segments to prevent transmission errors
Transport
binary equivalent of 167
10100111
keyword enables an HSRP router to take the active role immediately when it comes online
Preempt
Define inside and outside interfaces
1st step for NAT
Choose the odd-one-out:
● OSPF is a classful routing protocol.
● It uses cost to determine the best route.
● It converges quickly.
● OSPF routers discover neighbors before exchanging routing information.
classful routing
layer of the TCP/IP stack combines the OSI model physical and data link layers
Network access layer
hexadecimal value of C in binary
1100
value is used to determine the active router in an HSRP default configuration
Router IP address
all inside hosts get translated into one single IP address
NAT Overload (PAT)
110
default administrative distance of the OSPF routing protocol
layer in the OSI reference model is responsible for determining the availability of the receiving program and checking to see if enough resources exist for that communication
Application
equivalent of 11001010 in hexadecimal
CA
standards-based First Hop Redundancy Protocol is a Cisco supported alternative to Hot Standby Router Protocol
VRRP
Command will display a summary of the NAT configuration and number of active translation types on your router
